About building automation: where can I control it

turn on the air conditioner in the conference room and office without use for a long time; After work, lights, computers and air conditioners are running all night; If the plumber fails to come, the broken water pipe can only make it splash... These phenomena may have been staged in every office building. Is there a way that we don't have to do it ourselves, and these problems can be solved? Yes, this is the building automation system

building automation system (BAS) is a building management and control system that centrally monitors, manages and decentralizes the operation, safety status, energy use status and energy conservation management of power transformation and distribution, lighting, elevators, air conditioning, heating, water supply and drainage, fire protection, security and other decentralized equipment in buildings or building complexes, known as bas (buildingautomation-tem). Once the above problems occur, the system will automatically collect the information and notify the general control center so that it can be handled in time

what is the energy saving effect of building automation system? How to add value for users? With these questions, I came to Beijing Lida Group, which is located in the Beijing Economic Development Zone. Lida Group started with the development and production of automatic fire alarm system, and has now developed into a group company covering the design, development and production of several main businesses, such as fire protection system, building automation system, security system, electrical fire protection system, lightning protection system, environmental protection system and urban fire control system. The office building of the company is surrounded by several small four storey buildings, with a large garden like atrium in the middle and a transparent glass roof. This building structure consumes a lot of energy only for cooling in summer and heating in winter

Lida Hengxin Technology Development Co., Ltd., a subsidiary of the group, focuses on building automation business. Zhang Jun, manager of the company's marketing department, told: "it is of great significance to use and implement the requirements of the national green strategy. Building control systems can save energy, thus reducing the operating costs of large-scale equipment in buildings. It is inevitable that there will be a lot of noise in the working process. Saving is a kind of value-added."

take the office building of the company as an example. Its building area is 15000 square meters. Before the HBS type building automation system developed by Lida Group was used, the central air conditioning, lighting, power supply and distribution and other necessary facilities had been installed and used. The rated power of the central air conditioning system is about 600kW, and the rated power of lighting is about 240kw. Other loads were shared by water supply and drainage equipment, elevators, office equipment, etc., and the daily water consumption is about 40 tons

after the application of the HBS building automation system, the central air conditioning, water supply and drainage, power supply and distribution, lighting and other mechanical and electrical equipment of the building will be fully automated monitored to complete the comprehensive management of energy, and 496 monitoring points will be configured. According to the current situation, more than 200000 yuan of water and electricity will be saved in one year, and the investment in the building control system can be recovered in less than 2 years, while more than 2million yuan will be saved if the service life of general equipment is calculated as 10 years

according to the introduction, the HBS building automation system developed and produced by Lida Group is based on the BACnet protocol, an open international standard in the building control field. All software and hardware products in the system are products that follow this protocol, and can be used with other systems that support BACnet protocol for general and direct data exchange. The network support of HBS building automation system is Ethernet, so the generic cabling system of Ethernet can be used to realize equipment interconnection without other accessories. In addition, the HBS building control system can also automatically adjust the internal temperature, humidity, air quality, lighting intensity and the operation of related equipment according to people's needs, make personalized settings according to different people's feelings, and automatically store personal habit parameter curves to realize automatic adjustment and zoning adjustment

building energy conservation and comfort are the main goals of building intelligent buildings. In fact, intelligent buildings do not save energy or even are not intelligent. The focus of problems is mainly on the building automation system. Either the system has a high failure rate and a low degree of automation, or the system is running normally but the energy saving effect is not obvious, and some are simply in the shutdown state

according to the analysis of insiders, there are several main reasons for the above problems in intelligent buildings. First, there are great differences in product design ideas and application methods of various manufacturers, resulting in the design scheme unable to give full play to the performance of products. Second, most of the building automation products currently used are imported from abroad, and the core technical commissioning work is the responsibility of the supplier. Some foreign product suppliers do not provide complete technical data, and even implement technical blockade on the engineering integrator, so that the integrator can only be responsible for some simple auxiliary work. Third, many foreign suppliers did not realize the localization of product production and technical services, and the high service cost led to partial paralysis or shutdown of the system. In addition, the intelligent building has not entered China for a long time, many users lack systematic understanding of it, and most of them are taken care of by property companies in the actual operation process. Most of the operators have no higher education and can not cope with complex system operation and maintenance
